How deep can this filler repair in a single application? → Maximum 6mm per layer; deeper repairs require staged layers with 24 hours drying between each 2. Can it be used outdoors? → Yes, but priming before application and painting over the repair are both mandatory; not suitable for exterior timber with high water absorption 3. What is it not suitable for? → Movement cracks, structural repairs, unprimed metal, application below 5°C, and exterior timber prone to excessive water absorption — use Selleys No More Gaps® for moving cracks --- ## Product overview Selleys No More Cracks™ Large Cracks & Holes does what standard fillers can't: deliver reliable, lasting repairs on substantial surface damage. This ready-to-use, water-based acrylic filler is built for cracks and holes that need a serious solution. Manufactured by DuluxGroup Pty Ltd under the Selleys name, it bonds firmly with minimal shrinkage across a wide range of interior and exterior surfaces — plaster, mortar, concrete, timber, and primed metal. Where ordinary fillers stop at hairline cracks and cosmetic touch-ups, No More Cracks Large Cracks & Holes handles repairs up to 6mm deep. That makes it the right choice for older homes, high-traffic areas, and surfaces that have taken a beating from the elements. It comes as a smooth, easy-to-work paste in 230g Tottle, 230g Tub, 450g Tub, and 1kg Tub formats, so whether you're patching a single hole or working through a full renovation, there's a size that fits. --- ## Key features and what they mean in practice ### Water-based acrylic formula The water-based acrylic formula is what gives this product its versatility and strength. Acrylic fillers bond firmly to a wide range of substrate materials without the brittleness that comes with plaster-based alternatives. The water-based composition keeps VOC levels low, so you can work safely in enclosed indoor spaces. Clean-up is straightforward too — tools and excess product wash off with water before the filler cures. ### Superior adhesion with minimal shrinkage These two qualities work together to produce a repair that lasts. Strong adhesion locks the filler to the surrounding surface so it stays bonded rather than pulling away at the edges as it dries. Minimal shrinkage keeps the filled area flush with the surrounding surface after curing, so you're not going back for a second application because the repair has sunken. For fills up to 6mm, this combination matters most — deeper repairs put more stress on the material during drying, and inferior products show it. ### Multi-surface compatibility No More Cracks Large Cracks & Holes works across a full range of surfaces: - **Plaster** — the most common interior wall and ceiling material in Australian homes - **Mortar** — for repairs to brick joints, rendered walls, and masonry - **Concrete** — including floors, paths, and structural surfaces - **Timber** — for filling splits, knots, and nail holes in wooden surfaces - **Primed metal** — suitable for metal surfaces that have been primed beforehand That broad compatibility means one product handles most repair scenarios you'll face during a renovation or maintenance project, without needing a shelf full of specialised fillers. --- ## Technical specifications explained ### Dry time: what the numbers mean No More Cracks Large Cracks & Holes has two dry time specifications, each matched to the depth of the repair: - **Repairs under 2mm:** dry in approximately 2–3 hours - **Repairs up to 6mm:** dry in approximately 24 hours These figures reflect how water-based fillers work: as water evaporates from the acrylic paste, the material cures and hardens. Deeper fills hold more moisture and need more time. Sanding or painting before the 24-hour mark on a deep repair risks surface deformation, poor paint adhesion, or cracking — which means doing the job twice. Ambient conditions affect dry times too. High humidity, low temperatures, or poor ventilation will all extend drying. In cooler or more humid environments, allow extra time before moving to the next step. ### Maximum repair depth: 6mm The 6mm maximum depth is a genuine advantage over standard surface fillers, which typically handle repairs of just 1–2mm. For holes or cracks deeper than 6mm, build up the repair in layers — apply the first layer to a maximum depth of 6mm, let it dry fully, then add subsequent layers as needed. This staged approach maintains the integrity of the repair and prevents the excessive shrinkage that comes with applying large volumes of filler in a single pass. ### Available formats | Format | Best suited for | |---|---| | 230g Tottle | Small, targeted repairs; easy squeeze application | | 230g Tub | Small to medium repairs with blade application | | 450g Tub | Medium repairs or multiple smaller repairs | | 1kg Tub | Large-scale repairs or renovation projects | Choosing the right format means less waste and exactly the right amount of product for the job. --- ## Application guide ### Surface preparation Surface preparation is the foundation of a repair that lasts. Before applying No More Cracks Large Cracks & Holes: 1. **Clean the area** — remove all loose material, dust, paint flakes, grease, and debris from the crack or hole. A stiff brush or vacuum handles this well. 2. **Ensure the surface is dry** — moisture trapped beneath the filler undermines adhesion and extends dry times. 3. **Prime exterior surfaces** — for outdoor applications, priming before application is mandatory, not optional. 4. **Undercut deep cracks** — for cracks approaching 6mm, slightly undercutting the edges creates a mechanical key that locks in adhesion and strengthens the repair. ### Application method 1. Using a **filling blade or scraper**, press the filler firmly into the crack or hole, working it fully into the void to eliminate air pockets. 2. **Scrape off excess** material, leaving the repair slightly proud of the surrounding surface to allow for minor settling during drying. 3. Allow to **dry fully** — 2–3 hours for shallow repairs, 24 hours for deeper fills. 4. Once dry, **sand smooth** with fine-grit sandpaper until the repair sits flush with the surrounding surface. 5. The repaired area is ready for **priming and painting**. For the Tottle format, the squeeze-tube design allows direct application into narrow cracks without a blade, giving you precise control on smaller repairs. ### Layering for deep repairs For repairs exceeding 6mm in depth, build the repair in stages — never attempt to fill the full void in a single application. - Apply the first layer to a maximum depth of 6mm - Allow to dry completely (24 hours minimum) - Apply subsequent layers as required, drying between each - Sand and finish once the final layer has fully cured --- ## Exterior use: requirements and limitations No More Cracks Large Cracks & Holes is built for exterior applications, but a few requirements apply. **Mandatory requirements for exterior use:** - The surface must be **primed before application** - The repair must be **painted over** once dry — the filler is not designed to be left exposed to the elements long-term - The repair must be **protected from rain** until it has been painted **Surfaces not suitable for exterior use with this product:** - **Exterior timber prone to excessive water absorption** — repeated swelling and contraction in highly absorbent timber will stress the repair and cause it to break down over time For exterior timber with high moisture movement, a flexible sealant or a product specifically formulated for timber movement is the better choice. --- ## Limitations and when to use a different product No More Cracks Large Cracks & Holes is a high-performance filler, but it's built for specific applications. Using it outside those parameters won't give you the result you're after. ### Temperature limitation Do not apply below 5°C. At low temperatures, the water-based acrylic formula cannot cure correctly — the product may stay soft, bond poorly, or crack as temperatures fluctuate. In cooler months, confirm that both the ambient temperature and the surface temperature are above 5°C before and during application, and that temperatures will stay above this threshold throughout the full drying period. ### Movement cracks This product is not suitable for cracks where movement occurs — expansion joints, cracks caused by ongoing structural movement, or gaps between different building materials that expand and contract at different rates. A rigid filler applied to a moving crack will crack again as the substrate moves. That's not a product failure; it's the wrong tool for the job. For cracks and gaps subject to movement, **Selleys No More Gaps®** is the right solution. It's a flexible sealant built to accommodate movement, delivering lasting performance where a rigid filler would give way. ### Structural repairs No More Cracks Large Cracks & Holes is a surface filler, not a structural repair compound. It is not designed to restore load-bearing capacity to damaged surfaces. Cracks that indicate structural movement or damage need assessment by a qualified professional before any cosmetic repair is started. --- ## Storage and product care - **Seal the tub or tottle tightly** after each use to prevent the filler from drying out - **Store in a cool, dry location** away from direct sunlight and extreme temperatures - **Do not allow the product to freeze** — freezing permanently alters the consistency of the water-based formula and renders it unusable - If a skin forms on the surface of an opened tub, remove and discard it before use. The product beneath is typically still fine if it has been stored correctly --- ## Safety considerations As a water-based acrylic product, No More Cracks Large Cracks & Holes carries a low hazard profile compared to solvent-based fillers. Standard precautions still apply: - **Ventilation:** Keep airflow moving when working in enclosed spaces, particularly during sanding, where fine dust from dried filler can be an irritant - **Skin and eye contact:** Avoid prolonged skin contact with the wet product and keep it away from eyes. Wash hands thoroughly after use - **Sanding dust:** When sanding cured filler, wear a dust mask rated for fine particles to avoid inhaling particulate matter - **Disposal:** Do not dispose of wet product down drains. Allow small amounts to dry fully before disposal with general waste, or follow your local council guidelines for larger quantities --- ## Tips for better results - **Dampen highly absorbent surfaces slightly** before applying filler to bare plaster or mortar. This slows the rate at which the substrate draws moisture from the filler, improving adhesion and reducing the risk of premature drying at the bond interface. - **Use a flexible blade** rather than a rigid scraper for larger repairs. It gives you better control when feathering the edges into the surrounding surface, producing a smoother finish that needs less sanding. - **Prime before painting** — even on interior repairs. A coat of primer over the filled area seals the surface and ensures paint absorbs evenly. Skip this step and the repaired patch can show through as a dull spot in the finished coat. - **Work in moderate conditions:** the ideal application environment is between 10°C and 25°C with moderate humidity. Avoid applying in direct sunlight on hot days — rapid surface drying can cause the outer layer to skin over before the interior has cured, trapping moisture and leading to cracking. --- ## References -
